“‘There’s a law about Moore’s law,’ jokes Peter Lee, a vice-president at Microsoft Research: ‘The number of people predicting the death of Moore’s law doubles every two years.’”
In a recent Technology Quarterly article titled “After Moore’s Law,” The Economist magazine explored the possibilities of what’s next for semiconductor manufacturing once this long-standing industry expectation finally runs out of steam. For those unfamiliar with Moore’s Law, in 1965, Gordon Moore, a founder of Intel, wrote a paper on his observation that the number of electronic components on an integrated circuit doubles approximately every year.
Although the pace of circuit doubling eventually slowed to about once every two years, this observation – later known as Moore’s Law – has largely remained valid: Intel’s first microprocessor back in 1971 contained 2,300 transistors; today, advanced chips contain billions of transistors. However, as Lee alluded, maintaining this incredible rate of innovation is no small feat. Some device features are now so tiny that they are approaching a fundamental size limitation – the atom – which is why people are once again predicting the end of Moore’s Law.
The article provides an overview of chip electronics and alternative designs and materials, like FinFET and graphene, currently being used to continue scaling. It also explores the potential uses of quantum computing and other novel technologies to prolong device scaling and performance gains (see table below). One thing we know is ahead for the semiconductor industry: the ongoing need for innovation!
